The Dead Sea's salinity of 33.7 percent makes it 8.6 times saltier than the ocean. Bordering Israel, the West Bank and Jordan, it is 423m below sea level, making it the lowest place on land on Earth. A tourist hotspot for millennia, more than 1m visitors a year visit on the Israeli & Palestinian side alone. The view from the shore is one thing, but from the air, the sheer strangeness of the salt formations in and around the lake become readily apparent. Photos by Baz Ratner, of Reuters, and others.
